Agilent SB-CN Analytical HPLC Column 4.6x250 880975-905

The Agilent ZORBAX StableBond SB-CN Analytical HPLC Column (4.6 x 250 mm) is a cyano (CN) bonded-phase analytical column designed for HPLC separations. Manufacturer and authorized-distributor descriptions state it provides stable, reproducible separations for polar compounds and is suitable for applications in pharmaceutical, environmental, food, and biochemical research. The StableBond bonding chemistry is described as delivering enhanced stability under low-pH conditions and compatibility with common mobile phases.

Key Features:

• Column dimensions: 4.6 mm ID x 250 mm length
• Particle size: 5 µm
• Pore size: 80 Å
• Phase: ZORBAX StableBond CN (SB-CN)
• pH range: 1–8
• Maximum temperature: up to 80 °C (noted for some StableBond columns at low pH)
• Pressure rating: 400 bar

Advantages:

• StableBond chemistry provides enhanced stability at low pH for reproducible separations, as stated by the manufacturer/distributors.
• Reported to give excellent peak shape and retention for polar compounds, improving chromatographic performance for such analytes.
• Compatible with common mobile phases, including high aqueous-content solvents, enabling flexible method development.
• Applicable in multiple modes (reversed phase, normal phase, and SFC) per authorized distributor specifications.
